Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A channel switching method, comprising: obtaining, by a mobile Wi-Fi device, a channel switching instruction sent by a Wi-Fi access point that provides access to a network, the channel switching instruction carrying a destination channel identifier, and the mobile Wi-Fi device comprising a Wi-Fi client of the Wi-Fi access point and also a second Wi-Fi access point for a terminal to provide access to the network for the terminal by channeling communications to the Wi-Fi access point using the Wi-Fi client; and switching, by the mobile Wi-Fi device according to the channel switching instruction: a communication channel between the mobile Wi-Fi device and the Wi-Fi access point to a destination communication channel corresponding to the destination channel identifier, and a communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device for access to the network to the destination communication channel corresponding to the destination channel identifier by sending a switching instruction to the terminal from the mobile Wi-Fi device.
A mobile Wi-Fi device receives a channel switching instruction from a Wi-Fi access point. This instruction includes a destination channel identifier. The mobile Wi-Fi device acts as both a Wi-Fi client to the access point and a second Wi-Fi access point for a terminal (like a laptop or phone). The mobile Wi-Fi device then switches its communication channel with the main Wi-Fi access point and also instructs the connected terminal to switch to the same destination channel. This maintains connectivity for the terminal using the mobile Wi-Fi device's connection after the channel change. The switching to the new channel uses a switching instruction sent from the mobile Wi-Fi device to the terminal.
2. The method according to claim 1 , wherein the switching, by the mobile Wi-Fi device according to the channel switching instruction comprises: controlling, by the mobile Wi-Fi device according to the channel switching instruction, the communication channel between the mobile Wi-Fi device and the Wi-Fi access point to be switched to the destination communication channel corresponding to the destination channel identifier, and generating a switching completion signal; and switching, by the mobile Wi-Fi device according to the switching completion signal, the communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device to the destination communication channel corresponding to the destination channel identifier.
The channel switching process from the previous description starts with the mobile Wi-Fi device switching its connection to the Wi-Fi access point to the new destination channel. Upon successfully switching this connection, the mobile Wi-Fi device generates a "switching completion signal." Only after generating this signal does the mobile Wi-Fi device then switch the communication channel between itself and the connected terminal to the destination channel, ensuring the back-end Wi-Fi connection is stable before switching the front-end connection with the connected device.
3. The method according to claim 1 , wherein the switching, by the mobile Wi-Fi device according to the channel switching instruction comprises: controlling, by the mobile Wi-Fi device according to the channel switching instruction, the communication channel between the mobile Wi-Fi device and the Wi-Fi access point to be switched to the destination communication channel corresponding to the destination channel identifier; and at the same time controlling the communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device to be switched to the destination communication channel corresponding to the destination channel identifier.
The channel switching process from the first description involves switching the communication channel between the mobile Wi-Fi device and the Wi-Fi access point to the new destination channel. Simultaneously, the communication channel between the mobile Wi-Fi device and the terminal using it for network access is also switched to the same destination channel. Both connections are switched concurrently instead of sequentially, ensuring a faster switch to the destination channel.
4. The method according to claim 1 , further comprising: before the obtaining the channel switching instruction sent by a Wi-Fi access point: receiving, by the mobile Wi-Fi device, a termination instruction that is sent by the Wi-Fi access point and used for instructing the mobile Wi-Fi device to stop transmitting data; and terminating, by the mobile Wi-Fi device according to the termination instruction, data transmission performed by the mobile Wi-Fi device on the communication channel between the mobile Wi-Fi device and the Wi-Fi access point.
Before receiving the channel switching instruction, the mobile Wi-Fi device receives a "termination instruction" from the Wi-Fi access point. This instruction tells the mobile Wi-Fi device to stop transmitting data on the current channel. Upon receiving this termination instruction, the mobile Wi-Fi device ceases all data transmission on the communication channel between itself and the Wi-Fi access point, preventing data loss during the channel switch.
5. The method according to claim 4 , further comprising, after the terminating the data transmission: sending the termination instruction to the terminal that accesses the mobile Wi-Fi device to instruct the terminal to stop transmitting data on the communication channel on which the terminal communicates with the mobile Wi-Fi device.
Following the mobile Wi-Fi device terminating data transmission with the Wi-Fi access point as described in the prior step, the mobile Wi-Fi device then sends a termination instruction to the terminal connected to it. This instruction tells the terminal to also stop transmitting data on the communication channel between the terminal and the mobile Wi-Fi device, ensuring that both the mobile Wi-Fi device and the connected terminal have ceased sending data before the channel switch, leading to a more reliable switch.
6. The method according to claim 1 , further comprising: after the switching, by the mobile Wi-Fi device according to the channel switching instruction, sending, by the mobile Wi-Fi device, information comprising the destination channel identifier to the terminal that accesses the mobile Wi-Fi device, wherein the information is used to instruct the terminal to switch from the communication channel on which the terminal communicates with the mobile Wi-Fi device to the destination communication channel corresponding to the destination channel identifier.
After the mobile Wi-Fi device switches channels as described previously, it sends information including the destination channel identifier to the terminal connected to it. This information serves as an instruction for the terminal to switch from its current communication channel with the mobile Wi-Fi device to the new destination channel. This allows the terminal to seamlessly reconnect to the network via the mobile Wi-Fi device on the new channel after the mobile Wi-Fi device switches its Wi-Fi channel.
7. A channel switching apparatus, comprising: at least one hardware processor; a memory interfaced to the at least one hardware processor, the memory including instructions which control the at least one hardware processor to: obtain, by using a receiver in a mobile Wi-Fi device, a channel switching instruction sent by a Wi-Fi access point that provides access to a network, the channel switching instruction carrying a destination channel identifier, and the mobile Wi-Fi device comprising a Wi-Fi client of the Wi-Fi access point and also a second Wi-Fi access point for a terminal to provide access to the network for the terminal by channeling communications to the Wi-Fi access point using the Wi-Fi client; and switch, according to the channel switching instruction: a communication channel between the mobile Wi-Fi device and the Wi-Fi access point to a destination communication channel corresponding to the destination channel identifier, and a communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device for access to the network to a destination communication channel corresponding to the destination channel identifier carried in the channel switching instruction by sending a switching instruction to the terminal from the mobile Wi-Fi device.
A channel switching apparatus contains a processor and memory. The memory stores instructions that, when executed by the processor, cause the apparatus to receive a channel switching instruction from a Wi-Fi access point. This instruction includes a destination channel identifier. The apparatus acts as a Wi-Fi client for the access point and as an access point for a terminal. The instructions further control the apparatus to switch its communication channel with the main Wi-Fi access point and instruct the connected terminal to switch to the same destination channel. This maintains connectivity for the terminal using the apparatus connection after the channel change, with the switching using an instruction sent to the terminal.
8. The apparatus according to claim 7 , wherein the instructions further control the at least one hardware processor to: control, according to the channel switching instruction, the communication channel between the mobile Wi-Fi device and the Wi-Fi access point to be switched to the destination communication channel corresponding to the destination channel identifier, and generate a switching completion signal; and switch, according to the switching completion signal, the communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device to the destination communication channel corresponding to the destination channel identifier.
The channel switching apparatus from the prior description first switches its connection to the Wi-Fi access point to the new destination channel. Upon successfully switching this connection, it generates a "switching completion signal." Only after generating this signal does the apparatus switch the communication channel between itself and the connected terminal to the destination channel, ensuring stability before switching the client's connection. The instructions further control this sequence.
9. The apparatus according to claim 7 , wherein the instructions further control the at least one hardware processor to: control, according to the channel switching instruction, the communication channel between the mobile Wi-Fi device and the Wi-Fi access point to be switched to the destination communication channel corresponding to the destination channel identifier; and at the same time control the communication channel between the mobile Wi-Fi device and the terminal that accesses the mobile Wi-Fi device to be switched to the destination communication channel corresponding to the destination channel identifier.
The channel switching apparatus from the initial description switches the communication channel between itself and the Wi-Fi access point to the new destination channel. At the same time, it switches the communication channel between itself and the terminal also to the same destination channel. Both connections are switched concurrently using the instructions in memory.
10. The apparatus according to claim 7 , wherein the instructions further control the at least one hardware processor to receive, by using the receiver in the mobile Wi-Fi device, a termination instruction that is sent by the Wi-Fi access point and used for instructing the mobile Wi-Fi device to stop transmitting data; and terminate, according to the termination instruction, data transmission performed by the mobile Wi-Fi device on the communication channel between the mobile Wi-Fi device and the Wi-Fi access point.
The channel switching apparatus receives a termination instruction from the Wi-Fi access point before the channel switching instruction. This instruction tells the apparatus to stop transmitting data. Upon receiving this termination instruction, the apparatus ceases all data transmission on the communication channel between itself and the Wi-Fi access point using the instructions in memory.
11. The apparatus according to claim 10 , wherein the instructions further control the at least one hardware processor to send the termination instruction to the terminal that accesses the mobile Wi-Fi device to instruct the terminal to stop transmitting data on the communication channel on which the terminal communicates with the mobile Wi-Fi device.
This describes a feature of a **mobile Wi-Fi device** that also functions as a channel switching apparatus. This device acts as a Wi-Fi client to a primary Wi-Fi access point (AP) providing network access, and simultaneously serves as a secondary Wi-Fi AP for other connected terminals. The mobile Wi-Fi device channels the terminal's communications to the primary AP. In preparation for a potential channel switch or other network event, the mobile Wi-Fi device first receives a 'termination instruction' from the primary Wi-Fi AP. This instruction specifies that the mobile Wi-Fi device should stop transmitting data. Upon receiving it, the mobile Wi-Fi device immediately ceases its data transmission on the communication channel connecting it to the primary AP. Subsequently, the mobile Wi-Fi device forwards this same 'termination instruction' to the terminal(s) currently connected to it. This action instructs the terminal(s) to also stop transmitting data on their communication channel with the mobile Wi-Fi device, ensuring a synchronized halt of data flow across both the upstream and downstream links before further network operations.
